I highly recommend this product that can be applied on the screen the mobile without the formation of many bubbles. Besides, in my opinion, it is no no air bubbles as I often read in the reviews, but all simply a lack of adhesion of the film to some area of support. I have not managed to correctly apply despite cleaning rigorous of the screen. If it was the "bubble", it should be easy to evacuate the edge of the film, but it is not. If you do not want an unnecessary expense, do not buy it. This product deserves 0 stars.
